Powder Rheometer

In addition to the patented dynamic methodology, where a powder’s resistance to flow is measured whilst the powder is in motion, the FT4 also includes a shear cell for measuring the powder’s shear strength, a wall friction kit to quantify how the powder shears against the wall of the process equipment (in accordance withASTM Standard D7891), and also accessories for measuring bulk properties, such as density, compressibility and permeability. This range of measurement capabilities makes the FT4 a truly universal powder tester and the world’s most versatile instrument for measuring and understanding powder behaviour.
